TextView inside RecyclerView not scrolling

Question

I have a TextView that is inside a RecyclerView and those are both inside a fragment. When I try to scroll the Textview it just scrolls the RecyclerView instead.

Fragment Code

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/drink_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="100dp" />


    <Button
        android:id="@+id/rndDrinkBtn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="25dp"
        android:text="@string/random_drink"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

RecyclerView Item Code

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:theme="@style/Theme.BarBuddy.LightText">

   ...

    <TextView
        android:id="@+id/drink_instructions"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="20dp"
        android:layout_marginTop="30dp"
        android:layout_marginEnd="20dp"
        android:isScrollContainer="true"
        android:maxHeight="52dp"
        android:scrollbars="vertical"
        android:text="null"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/drink_name" />


   ...

</androidx.constraintlayout.widget.ConstraintLayout>

I want to be able to scroll both the Textview and RecyclerView separately.

Obviously the recyclerView will consume the touch event, so when scrolling the textView the recyclerView will scroll.

You can intercept this by setting a touch listener to your textView inside the ViewHolder:

 textView.setOnTouchListener(object : View.OnTouchListener {
 override fun onTouch(v: View?, event: MotionEvent?): Boolean {
  
  return true
 }

This worked great! Just had to get the parent element and disallow touch events for it while touching the TextView – Tyren Cleasby Jan 14 '23 at 22:45
